By applying gravity type refrigerant distribution system, reliable operation is provided, and evaporation efficiency is improved by optimizing arrangement of eliminator and evaporator tube.

The oil supplied during the high-speed rotation of the compressor is recovered through a three-stage separation system. When refrigerant is moved, it prevents impurities from entering and improves cooling efficiency. By continuously supplying and recovering oil, oil shortage can be prevented.

Valuable floor space can be saved by reducing installation area and weight.

It minimized turbulence in intake port and reduced inconvenience of noise by preventing outflow.

It stores and analyzes operation record for quick diagnosis to provide solution in case of failure.
